X-ray photoelectron spectroscopy analysis of the copper/arachidic acid organized molecular assembly interface: Charging phenomena
- Measurements and Characterization Branch, National Renewable Energy Laboratory, Golden, Colorado 80401 (United States)
Interactions of evaporated copper with the methyl terminated surfaces of self-assembled monolayers of arachidic acid were studied with x-ray photoelectron spectroscopy (XPS). The arachidic acid [CH[sub 3](CH[sub 2])[sub 19]COOH] organized molecular assemblies (OMAs) were self-assembled on native oxide grown on freshly prepared 200 nm thick aluminum films on single crystal silicon wafers. XPS spectra were acquired as a function of evaporated copper thickness. Charging shifts of up to 0.84 eV were observed for the C(1[ital s]), O(1[ital s]), and Cu(2[ital p]) photoemission lines during evaporation of up to 4.0 nm of copper. The thickness of the organized molecular assemblies (OMA) is approximately 2.7 nm on the native oxide surface, yielding a total thickness for the oxide/OMA stack of 6--7 nm.
